— More than 70 million fans will attend Major League Baseball games for the first time in six years, a post-pandemic rebound for a sport that instituted its biggest on-field changes in decades.

A pitch clock to speed play — game times are down 24 minutes to 2:40 for nine-inning games — limits on defensive shifts to increase offense, new social spaces at ballparks and technology innovations to speed entry have factored into a 9.2% rise in average attendance to 29,176. Expanding the playoffs to 12 teams, which began last year, led to more than half the teams remaining in mathematical contention.

"Getting back above 70 million is an accomplishment for us," baseball Commissioner Rob Manfred said Wednesday. "I think it's the playoff format, balanced schedule, the rule changes this year in terms of the product, the stuff clubs have done locally in terms seating options."

Still, the average attendance remains below the record high of 32,785 in 2007 and MLB hasn't reached 30,000 since 2017.

"We want to be a 70-plus-million-fan business year after year. We want that to become routine for us," Manfred said. "I think we need to be a little realistic about the effect of, particularly in some of our bigger markets, smaller ballparks limit your ability to get to the absolute peak that you saw some years ago."

Attendance is based on tickets sold, not fans who actually walk through turnstiles. The league brought in 68.55 million fans through Wednesday and advance sales for weekend series meant 70 million is essentially assured.

Twenty-four teams were up, led by NL champion Philadelphia and Cincinnati. Of the six clubs with decreases, just two dropped by six figures: the Chicago White Sox and Washington.

Combined with the minors, baseball will top 100 million fans. Minor leagues drew around 32.1 million for 7,884 dates, an average of 4,076 and up 3.9%.

Marketing throughout the sport has been revolutionized.

"In the '90s and 2000s, generally when you would try to market a fan coming to a ballpark, you would do so through traditional marketing methods and that would include everything from putting billboards out there or putting radio spots or TV spots or print ads," Atlanta Braves President Derek Schiller said.
